Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a port transport trailer towed by a motor vehicle.

(Prior art) Conventional trailers for transporting boats generally have axle and wheels attached to a frame on which the boat is placed and are towed by a car. We decided to move the entire trailer into the water so that only the boat floated, and to pull it out of the water, we pulled the boat above the submerged trailer and pulled the boat out at the same time as the trailer, but each time the trailer itself ended up submerged in water. Due to rust, etc., the trailer quickly becomes damaged and its durability deteriorates, and complete anti-corrosion measures not only require a high cost, but also require maintenance such as wiping the trailer with water every time it is used. There is also the problem that the amount of energy required is also large.

Furthermore, since the trailer is towed by a car, the trailer must be moved exclusively by the car, which also has the disadvantage of restricting its handling in narrow places such as shores.

In general, this is not a problem if it is a small boat, but in the case of a medium or large boat, the above method is often difficult due to its size and weight. It is necessary to use a crane installed on the shore or a special elevating device to raise and lower the
2-51440, Utility Model Publication No. 55-16797, Special Publication No. 56-41475, Special Publication No. 57-61634), not only are there limited places for boats to enter the water, but the equipment has also become large-scale. Another problem is that it is no longer possible to enjoy boating easily anywhere.

There are also many maintenance items for boats, such as the battery installed on the boat that must be sufficiently charged when the boat is in use, and this also requires a great deal of effort to carry out within the normal limited time. There are also some points that need improvement.

(Purpose) In view of the above-mentioned problems, the present invention is a trailer for transporting a boat that is towed by a car, but has durability that can be used independently in any location, and does not allow the trailer body to be submerged in water. The purpose of the present invention is to provide a trailer for transporting a boat, which has the convenience of allowing the boat to be raised and lowered from the water surface without the need for additional equipment or devices other than the trailer, and which can reduce the maintenance and management of the boat. shall be.

(Structure) In order to achieve the above-mentioned object, the present invention provides a trailer for transporting a boat towed by an automobile, in which a boat mounted on the main frame is mounted on the main frame constituting the chassis portion of the trailer main body. A sub-frame for guiding the trailer above the water surface is retractably housed, and the sub-frame intersects with a first frame that can be pulled out from the rear end of the main frame in the direction of the entire length of the trailer body. A second frame is detachably attached to the second frame and slidably supports the bottom of the boat to be guided. The trailer body consists of a removably attached auxiliary frame, and a powered winch that pulls the boat, which is moved by its own weight from the main frame to the auxiliary frame, from the front of the trailer body using a cable, and This system is characterized by the provision of a self-propelled device that uses power as a drive source to drive the trailer body, and an auxiliary power generator that charges the storage batteries of the boat and trailer while the trailer is running.

First, in the chassis part 2, as shown in FIGS. 2 and 3, a base frame 21 is made of square steel pipes made into a ladder shape by welding, etc., and a thin round steel pipe that is weaker in strength than the base frame 21 is used as the base frame 21. A main frame 20 is formed with a guard frame 22 welded or bolted around the main frame 20, and at one end of the base frame vertical tube 21a, rubber rollers for smoothly moving the boat are placed at appropriate positions inside the main frame 20. A substantially ship-shaped sub-frame 23 is provided.

The sub-frame 23 is made of a bar and has a substantially U-shaped planar first frame 24. Auxiliary wheels 25.Foldably fixed to the first frame central portion 24a and waterproofed by filling with grease, etc. The U-shaped second frame 2 is detachably attached to the upper surface of the first frame side parts 24b with pins.
6. It is constituted by approximately E-shaped auxiliary legs 27 that are removably attached to the lower surface of the first frame side portions 24b with bisques. The central portion 27a of the auxiliary leg 27 is long, the front and rear end legs 27b, 27c are short, and the auxiliary leg 27 has an E-shape close to an inverted chevron.

1st frame 2 with M2 frame 26 etc. trimmed
4, the first frame side portions 24b have a cross-sectional shape that fits loosely within the base frame vertical tube 21a, and are slidably inserted and stored within this tube, and conversely, the first frame side portions 24b are
When the frame 24 is pulled out, it forms an extension of the base frame vertical tube 21a.

Further, when the first frame side parts 24b are pulled out to a predetermined length, the stoppers 21b provided at the tips of the base frame vertical tubes 21a are pulled out from the first frame side parts 24b, as shown in FIG.
It falls into the hole of the stopper receiver 24c provided at the tip of the frame 4b so that it can be bent freely, and prevents the sub frame 23 from falling out when removed from the main frame 20. Roughly, the first frame both sides 24b fall into the base frame vertical pipe 21a. When the device is stored in the device, a locking device 1 (not shown) is used to prevent the device from falling out.

Furthermore, when the second frame 26 and the auxiliary legs 27 are removed from the first frame 24, they are placed and stored in the guard frame 22.

At the front of the main frame 20, a Y-shaped bow support 28 is provided to support the bow of the boat, and also includes a joint 29a with the towing vehicle, a damper 29b for damping, and a joint 29a for supporting the bow of the boat. A back lock 29C that prevents the part 29a from digging into the main frame 2o, a foldable front wheel 29d with a handle, and a lever 2 that releases the brake of the rear wheel of the self-propelled part 4, which will be described later.
9e are provided respectively.

In the longitudinal center of the main frame 20, a plurality of rubber O-ra rubbers R supporting the bottom part of the boat are arranged at appropriate positions, and the line of the rubber rollers R is connected to the main frame 20.
o is slightly sloped from the front to the rear, making it easier for the boat to slide off.

In the figure, reference numeral 61 indicates lamps such as side lights and brake lights of the trailer 1, and 62 indicates side lamps that illuminate the sides of the trailer 1. In general, it is also possible to extendably attach a stabilizing stand (not shown) to the main frame 20 to support the trailer 1 more stably.

Next, the power unit 3 is operated as shown in FIG.
A motor 32 that can be rotated in forward and reverse directions from the electricity of the main generator 31. The transmission 33 is configured to input the rotation of the motor 32 through an interrupter (not shown).

The rotation from the transmission 33 of the power unit 3 is supplied to two systems, the self-propelled unit 4 and the winch unit 5.

The self-propelled gB4 is connected by a universal joint etc. 1 to the professional rushst 41. Differential gear 42. It is composed of a rear axle and wheels 43 that support the chassis part 2 via a suspension (not shown), and transmits rotation from the transmission 33 to the rear axle 43 to rotate the trailer 1.
At the same time, by operating a brake (not shown) using a brake lever 29e, a braking function is also provided.

Note that the rear axle 43 uses double tires when transporting a large boat.

Further, the rotation from the transmission 33 is appropriately interrupted by the interrupter 46, and when the vehicle is towed by a car, the rotation from the rear wheels 43 is interrupted.
The front wheel 2 is used for steering when it rotates freely and moves on its own.
Performed by Hashidr 9d.

Further, a power generation pulley 44 is provided on the differential gear 42, and an auxiliary generator 45 attached to the chassis portion 2 is driven by a belt to generate power, and the battery installed in the trailer 1 and the boat is charged while the rear axle 43 is rotating. .

The winch unit 5 includes a first pulley 51 with an electromagnetic clutch rotated by a belt drive from the mission 33, and
A winch shaft 53 having a pulley 51 at one end and a 27th pulley 52 at the other end. In order to balance the weight of the trailer 1, the winch 54 is arranged at the rear of the trailer 1 and receives input from a second pulley 52 by changing the direction of rotation. The wire 55 that has been extended to the vicinity is wound up.

In addition, a crank (not shown) can be freely attached to the winch 54 so that it can be manually rotated, and a mechanical or electrical sensor is installed near the bow receiver 28 of the chassis section 2, and an electromagnetic sensor is installed on the first pulley 51. It has an automatic stop function that automatically stops the movement of the wire 55 when the boat is pulled up to a fixed position on the trailer by activating the clutch.

Transporting the boat T using the trailer 1 having the above configuration, lowering it onto the water surface, and lifting it up will be explained.

During transportation, the boat T is supported by a bow support 28° rubber roller rack, etc., and at the same time, the main frame 20 and the boat T are fixed by a fixed wire or the like.

Furthermore, while the trailer 1 is running, the batteries at the port T and the like are charged by the auxiliary generator 45, which reduces the labor involved in managing the boat.

Next, in places where the boat T is dropped off, roads are narrow, curves are tight, etc., even if the trailer 1 cannot move freely due to the difference in inner wheels with the trailer 1 when towed by a car, the self-propelled section 4 This makes it possible to move in narrow spaces, and when moving a trailer, whether towed or self-propelled, the trailer 1
If the guard frame 22 collides with or comes into contact with surrounding objects,
Since the guard frame 22 is weaker in strength than the base frame 21, it can act as a buffer to minimize damage to the trailer 1, and furthermore, this repair can be completed by replacing only the guard frame 22.

Next, the assembly of the subframe 23 will be explained.
Holding the first frame center portion 24a, pull out the first frame side portions 24b from the base frame vertical tube 21a, and when a predetermined length is reached, the stopper 21b is moved to the stopper receiver 24c.
, and the base frame vertical tube 21a is attached to the first frame both sides 2.
4b, the two second frames 2 stored in the guard frame 22 are
6. By fixing the auxiliary legs 27 to the upper and lower surfaces of the first frame 24 with pins, the substantially boat-shaped sub-frame 23 is assembled (see FIG. 2).

Next, if the trailer 1 is moved from the gently sloping shore by the car or self-propelled unit 4 and the sub-frame 23 is submerged in water, the central leg 27a of the auxiliary leg 27 is long and the front and rear end legs 27b, 27c are short. , the sub frame 2 is tilted, and the sub frame 2 is supported by the auxiliary wheels 25 and the auxiliary legs 27.
3 is close to a slide between the main frame 20 and the water surface, and can guide the boat T onto the water surface (
(See Figure 5 (a)).

In this case, the main frame 20 of the trailer 1 will not be submerged in water, but only a part of the sub-frame 23 will be submerged in water, and it is sufficient to take anti-corrosion measures only for the sub-frame 23, without incurring any cost. Durability is significantly improved.

Next, remove the fixed wire of the boat T, and attach the wire 5 to the bow of the boat.
The winch 54 sends out the wire 55 and rotates to slide the boat T toward the water surface along the subframe 23. At this time, even if the sliding speed of the boat T increases, the winch 54 Since the sending speed is constant, the boat T can be easily lowered to the water surface while acting as a brake to prevent the boat T from falling suddenly.

Next, the boat T on the water surface! To pull up, use winch 5
The boat T can be pulled up while sliding on the sub-frame 23 by rotating the wire 55, and the automatic stop function of the winch 54 prevents excessive winding of the wire 55 (see Fig. 5 (b)). ).

Then, the boat T pulled up above the main frame 20 is fixed to the guard frame 22 with a fixed wire or the like, the second frame 26 etc. are removed, the sub frame 23 is disassembled, and the first frame both sides 24b are attached to the base frame vertical tube 21a. By storing and locking the boat inside, the work of raising the boat T can be easily completed.

As described above, raising and lowering the boat T on the water surface can be easily carried out using only the trailer 1 without requiring any separate special equipment or equipment.

In the above embodiment, a steel pipe was used as the main frame, but for example, the main frame is made of a steel material with a U-shaped cross section, and the first flume can be slid and stored in this groove. Other materials of any cross-sectional shape that can be polymerized may also be used.

Further, in the above embodiment, the power section was configured with a generator and a motor, but it is also possible to use another power source such as a gasoline engine.
Also, regarding the placement of heavy objects such as generators,
The arrangement is not limited to the above-mentioned embodiment, and although the rear axle is also one axle in the above-mentioned embodiment, this may be used as a trailer with two or more wheels and the front wheels may be two or more instead of one. .

(Effects) As described above, according to the present invention, in a trailer for transporting a boat towed by an automobile, a sub-frame for guiding the boat onto the water surface is retractably housed in the main frame of the trailer, and the sub-frame It can be assembled and disassembled at the rear end of the main frame, and also includes a powered winch that raises and lowers the boat using a cable, a self-propelled device that uses this power as a drive source to run this trailer, and a motorized winch that moves the boat while the trailer is running. The trailer is equipped with a power generator and an auxiliary power generator to charge the battery installed in the trailer, so even though it is a trailer for transporting boats, there are no restrictions on where the boat can enter the water, and it can be used at low cost without submerging the trailer itself. It is possible to take anti-corrosion measures to improve durability, and there is no need for equipment or equipment other than the trailer to raise and lower the boat, and the boat can be maintained by charging while the trailer is moving. Management can be reduced.

Furthermore, since the main frame is made of a material that is weaker in strength than the base as a shock absorbing member, there is less damage caused by collisions with trailers, etc., and repairs can be easily performed.
